Rotors and pads on ebay

Ebay has some great deals on pads and rotors for my 96 C4 - approx
$200 +/-. for a set of all four. (erotorshop, etop line, US Rotors,
others). Here's a sample url:

Does anybody have any recommendations or comments to make about these
deals?

I went back to the mechanic that gave me a high estimate for replacing
the set and he agreed that I could supply the parts and he would
charge me $250 for labor. A little high but much more reasonable than
his $800 price for parts. He also suggested I get the caliper kits in
case the seals need replacing. But I don't find those on ebay and
that would be another $120 at Ecklers. Is that reasonable?

Nothing from ECKLERS is reasonable !!!! Go to Auto Zone or NAPA or Auto
Discount...their parts are excellent..why do Vette owners always want to go
to ecklers etc..its just another GM car that uses standard replacement
parts..in fact most of the parts are better than the cheap low bidder
extremely overpriced stuff that GM sells.....
